To all whom t may concern/.-

Be it known that I, J osEPH MITCHELL PAYNE, a citizen of the UnitedStates, residing at Cressona, in the county of Schuylkill and State ofPennsylvania, have invented a new and useful Improvement in Electric-Brake Apparatus, of which the following is a speciiication.

My invention relates to an improvement in electric-brake apparatus forrailway-cars and in couplings for the same; and it consists in thepeculiar construction and combination of devices that will be more fullyset forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of a railway-carprovided with coupling devices and an electric brake embodying myimprovements and showing the manner of coupling the cars together. Fig.2 is a bottom plan View of the same. Fig. 3 is an end elevation of thecar. Fig. a is a detail perspective view of the coupling. Fig. 5 is asectional View of the same, showing the draw-heads coupled together.Fig. 6 is a sectional view taken on the line .fr of Fig. 5.

A represents the draw-heads, which are pivoted to draw-bars B, that aresecured under the ends of the car C in the usual manner and are providedwith the usual buffersprings D, the draw-bars being movablelongitudinally under the car. Each draw-bar is provided on oppositesides with ears E. Each draw-head is provided with a pair ofrearwardextending oppositely-inclined shoulders F, arrangedsubstantially in the form 'of an airow-head. The said shoulders F of onedrawhead are provided with rearward-extending pins G, and the shouldersof the companion draw-head have openings H to receive the pins, theinner sides of said openings being flared outwardly, as shown in Fig. 6,to` permit the pins G to Work loosely therein when the cars are coupledtogether, thus rendering the coupling flexible and enabling the cars toreadily pass around curves.

-A lever I is pivoted on each end of each car and connected to one ofthe draw-heads by a chain or link K, each of the said levers engaging adetent or ratchet-plate L, and thereby enabling the draw-head to besupported at any desired elevation, and the function of the leversbeing, also, to lower the draw-heads in the act of uncoupling.

M represents rock-shafts journaled in the trucks of each car, midwaybetween the axles thereof, said rock-shafts having upward-extending armsN.

O represents the brake-shoes, which are pivoted in the truck at theirupper ends and are adapted to engage the car-wheels. The saidbrake-shoes are connected to the rock-shafts M by links P. Attached toeach arm N is a rod R, which is guided horizontally under the car bysupports or brackets S, and has at its inner end an armature T.

Secured under the bottom of the car are electro-magnets U, having theirpoles presented toward the said armatures, but out of contact therewith.In one of the cars, or in the tender of the locoinotive,.is an electricbattery V, having its terminals connected in series with theelectro-magnets II throughout the entire length of the train, thecouplings between the conductors IV of said battery and electro-magnetsbeing effected between the cars by arrow-head-shaped electrodesX andelectrodes Y, having clamps Z to engage the same. The said couplingdevices are secured in transverse openings in the ears E of thedraw-bars, as shown in Figs. 1, 2, and Il. Included in the conductors lVis a circuitcloser A', which is normally open, as shown in Fig. 2.

In order to apply the brakes it is only necessary to close thiscircuit-closer, and thereby cause the current of electricity to excitethe electro-magnets II, when the armatures T will be attracted by thesaid magnets and cause the rods R to be moved lengthwise and partlyrotate the rock-shafts IWI and cause the links P thereof to apply thebrake-shoes to the wheels, as will be very readily understood.

Having thus described my invention, I claiml. The draw-bars providedwith laterallyextending ears provided with perforations, in combinationwith the electrodes X Y, supported in said perforations, substantiallyas set forth.
